Does contracting out lead to improvement in service volumes at primary and secondary health services? Evidence from rural districts of Sindh, Pakistan.

OBJECTIVE: To determine the improvement in service volumes from baseline, if any, in the contracted out primary and secondary healthcare facilities against key performance indicators, and to explore the perceptions of health managers and experience of patients in this regard. METHODS: The mixed-method study was conducted at Aga Khan University, Karachi, from November 2019 to April 2020, and comprised secondary data extracted from the district health information system related to Thatta and Sujawal districts of the Sindh province of Pakistan from July 2016 to June 2019. Apart from data analysis for baseline versus end-line comparison of key performance indicators, the study also comprised of a cross-sectional survey of health facilities, patient exit interviews and in-depth interviews with healthcare managers. RESULTS: The key performance indicators showed improved service volumes compared to the baseline. All services, including general outpatient department (33%), consultancy services (91%) and emergency services (106%) increased in volumes. Facility-based deliveries increased by 37% and antenatal care visits increased by 100% but immunisation volumes declined. Specialist workforce increased by 47%. Healthcare managers perceived delayed/partial budget release as the key determinant of staff retention, availability of drugs, equipment, supplies, water and electricity at health facilities. Lack of control over government-appointed employees coupled with political interference created workforce shortage. Patients were satisfied with service delivery, but unavailability of medicine was the main concern for 64.3%. CONCLUSIONS: Contracting out showed improvement in service volumes, but lack of autonomy over budget allocation and utilisation, staff appointment and poor coordination among the stakeholders were key barriers.

Overcoming the challenges of community-engaged emergency referrals in a rural district of Pakistan.

A functional referral system for addressing health emergencies requires coordinated efforts by health system's stakeholders and the community. Using the Rural Health Programme (RHP) Thatta as a platform provided by an academic institution, district health system stakeholders and the community of Mirpur Sakro, taluka of Thatta, were engaged to strengthen the referral system for health emergencies through active community engagement. Through consultations with stakeholders, a referral system plan was developed with community volunteers from each village as focal persons for transportation, referring patients to health facilities and maintaining referral documentation. The stakeholders' experience and perceptions about the referral system were assessed through qualitative in-depth interviews. Patients' experiences of referral system improved with enhanced transport availability, but they faced structural challenges, including out of pocket transport expenses, weak back-referral links, lack of trust between the community and healthcare providers and poor availability of medicines.

RSV associated hospitalizations in children in Karachi, Pakistan: Implications for vaccine prevention strategies.

Major progress is being made in vaccines against Respiratory Syncytial Virus (RSV), with multiple vaccine candidates currently in the clinical phase of development. Making an investment case for public sector financing of RSV vaccine will require estimation of burden, cost-effectiveness, and impact. The aim of this study is to determine the proportion, age distribution and clinical spectrum of RSV associated hospitalizations in children in Karachi, Pakistan. A three years prospective study was conducted at the Aga Khan University Hospital in Karachi, a city of 20 million in south Pakistan, from August 2009 to June 2012. Children less than five years old admitted with acute respiratory infections (ARI) were enrolled. Throat swabs were collected and tested for RSV using real-time PCR. Multivariable log binomial regression analysis was performed to identify the associated factors of RSV infection. Out of 1150 children enrolled, RSV was detected among 223 (19%). Highest rate of RSV detection was in young infants less than 3 months of age (48/168, 29%), which accounted for 22% of all RSV detected. Most common diagnosis in RSV positive infants (<12 months of age) was bronchiolitis followed by pneumonia, while in older children between the ages of one and 5 years of age, pneumonia and asthma were the most common diagnosis. Although identified year-round, RSV was most prevalent from August to October with peak in September, coinciding with the rainy season. This study identified RSV to be independently associated with younger age (P = 0.036), rainy season (P < 0.001), post-tussive emesis (P = 0.008), intubation (P = 0.003), and discharge diagnosis of bronchiolitis (P = 0.004). Vaccines against RSV that target this age group are likely to yield remarkable benefit.

Schools of public health in low and middle-income countries: an imperative investment for improving the health of populations?

BACKGROUND: Public health has multicultural origins. By the close of the nineteenth century, Schools of Public Health (SPHs) began to emerge in western countries in response to major contemporary public health challenges. The Flexner Report (1910) emphasized the centrality of preventive medicine, sanitation, and public health measures in health professional education. The Alma Ata Declaration on Primary Health Care (PHC) in 1978 was a critical milestone, especially for low and middle-income countries (LMICs), conceptualizing a close working relationship between PHC and public health measures. The Commission on Social Determinants of Health (2005-2008) strengthened the case for SPHs in LMICs as key stakeholders in efforts to reduce global health inequities. This scoping review groups text into public health challenges faced by LMICs and the role of SPHs in addressing these challenges. MAIN TEXT: The challenges faced by LMICs include rapid urbanization, environmental degradation, unfair terms of global trade, limited capacity for equitable growth, mass displacements associated with conflicts and natural disasters, and universal health coverage. Poor governance and externally imposed donor policies and agendas, further strain the fragile health systems of LMICs faced with epidemiological transition. Moreover barriers to education and research imposed by limited resources, political and economic instability, and unbalanced partnerships additionally aggravate the crisis. To address these contextual challenges effectively, SPHs are offering broad based health professional education, conducting multidisciplinary population based research and fostering collaborative partnerships. SPHs are also looked upon as the key drivers to achieve sustainable development goals (SDGs). CONCLUSION: SPHs in LMICs can contribute to overcoming several public health challenges being faced by LMICs, including achieving SDGs. Most importantly they can develop cadres of competent and well-motivated public health professionals: educators, practitioners and researchers who ask questions that address fundamental health determinants, seek solutions as agents of change within their mandates, provide specific services and serve as advocates for multilevel partnerships. Funding support, human resources, and agency are unfortunately often limited or curtailed in LMICs, and this requires constructive collaboration between LMICs and counterpart institutions from high income countries.

Prevalence of hepatitis B virus infection among barbers and their knowledge, attitude and practices in the district of Sukkur, Sindh.

OBJECTIVES: Several occupations in developing countries lag behind in ensuring the safety of their workers in occupational settings. Lack of implementation of safety guidelines at workplaces can expose workers to health risks. In Pakistan, barbers are one of the un-regulated occupational groups. Low literacy, increased frequency of direct skin contact and blade/razors use can expose barbers to body fluids including blood of the customers. We conducted this study in order to determine hepatitis B virus (HBV) prevalence among barbers and their knowledge, attitude and practices in a peri-urban district of Sindh. MATERIAL AND METHODS: Three hundred eighty-five barbers from the Sukkur district were interviewed using a structured questionnaire. Blood samples were collected and tested for HBsAg. A scale was built to determine the proportions of responses to knowledge, attitude and practice items. RESULTS: The prevalence of HBV among barbers was 2.1%. The barbers' knowledge on HBV and its transmission routes was poor. The response to attitude items was good, except that only 35.1% of the participants agreed to have vaccination against HBV. The overall performance on the knowledge and practice scales was poor compared to the attitude scale on which 80% of the barbers performed well. CONCLUSION: The prevalence of HBV among barbers was lower compared to the available national figures for the prevalence among the general population.

Protest of doctors: a basic human right or an ethical dilemma.

BACKGROUND: Peaceful protests and strikes are a basic human right as stated in the United Nations' universal declaration on human rights. But for doctors, their proximity to life and death and the social contract between a doctor and a patient are stated as the reasons why doctors are valued more than the ordinary beings. In Pakistan, strikes by doctors were carried out to protest against lack of service structure, security and low pay. This paper discusses the moral and ethical concerns pertaining to the strikes by medical doctors in the context of Pakistan. The author has carefully tried to balance the discussion about moral repercussions of strikes on patients versus the circumstances of doctors working in public sector hospitals of a developing country that may lead to strikes. DISCUSSION: Doctors are envisaged as highly respectable due to their direct link with human lives. Under Hippocrates oath, care of the patient is a contractual obligation for the doctors and is superior to all other responsibilities. From utilitarian perspective, doctors' strikes are justifiable only if there is evidence of long term benefits to the doctors, patients and an improvement in service delivery. Despite that, it is hard to justify such benefits against the risks to the patients. Harms that may incur to the patients include: prolongation of sufferings, irreversible damage to health, delay in treatment, death, loss of work and waste of financial resources.In a system of socialized medicine, government owing to greater control over resources and important managerial decisions should assume greater responsibility and do justice to all stakeholders including doctors as well as patients. If a doctor is underpaid, has limited options for career growth and is forced to work excessively, then not only quality of medical care and ability to act in the best interests of patients is adversely affected, it may also lead to brain drain. SUMMARY: There is no single best answer against or in favor of doctors' industrial action. The author calls for the debate and discussion to revitalize the understanding of the ethical predicaments of doctors' strikes with patient care as the priority.

Burden of skin lesions of arsenicosis at higher exposure through groundwater of taluka Gambat district Khairpur, Pakistan: a cross-sectional survey.

Prior surveys conducted have found higher proportion of arsenic-contaminated wells in villages along river Indus in Pakistan. This study aims to determine the prevalence of arsenicosis skin lesions among population exposed to higher exposure in taluka Gambat district Khairpur in Sindh. The cross-sectional survey was conducted from August 2008 to January 2009 among 610 households. A total of 707 water sources (hand pumps/wells) were tested from the villages of union councils of Agra and Jado Wahan for arsenic levels with Quick rapid arsenic field test kits. A total of 110 households exposed to arsenic levels >50 ppb were identified. Case screening for arsenic skin lesions was performed for 610 individuals residing in these 110 high-risk households. Information regarding household and socio-demographic characteristics, height and weight measurements and arsenic exposure assessment were collected. Physical examinations by trained physicians were carried out to diagnose the arsenic skin lesions. After data cleaning, 534 individuals from all age groups were included in the final analysis which had complete exposure and outcome information. Overall prevalence of arsenicosis skin lesions was 13.5 % (72 cases). Of the 534 individuals, 490 (91.8 %) were exposed to arsenic levels of ≥100 ppb in drinking water (8.2 % to >50-99 ppb, 58.6 % to 100-299 ppb, 14.6 % to 300-399 ppb and 18 % to ≥400 ppb). Prevalence rate (per 100 population) of arsenicosis was highest at arsenic levels of 100-199 ppb (15.2 cases) followed by ≥400 ppb (13.5 cases) and 300-399 (12.8 cases). Prevalence rate was higher among females (15.2) compared to males (11.3). Our study reports arsenicosis burden due to exposure to higher arsenic levels in drinking water in Pakistan. Exposure to very high levels of arsenic in drinking water calls for urgent action along river Indus. Prevalence of skin lesions increases with increasing arsenic levels in drinking groundwater. Provision of arsenic-free drinking water is essential to avoid current and future burden of arsenicosis in Pakistan.

Correlation of respiratory symptoms and spirometric lung patterns in a rural community setting, Sindh, Pakistan: a cross sectional survey.

BACKGROUND: Symptom-based questionnaires can be a cost effective tool enabling identification and diagnosis of patients with respiratory illnesses in resource limited setting. This study aimed to determine the correlation of respiratory symptoms and spirometric lung patterns and validity of ATS respiratory questionnaire in a rural community setting. METHODS: This cross sectional survey was conducted between January - March 2009 on a sample of 200 adults selected from two villages of district Khairpur, Sindh, Pakistan. A modified version of the American thoracic society division of lung disease questionnaire was used to record the presence of respiratory symptoms. Predicted lung volumes i.e. forced vital capacity (FVC), forced expiratory volume in one second (FEV1) and their ratio (FEV1/FVC) were recorded using portable spirometer. RESULTS: In the study sample there were 91 (45.5%) males and 109 (54.5%) females with overall mean age of 34 years (±11.69). Predominant respiratory symptom was phlegm (19%) followed by cough (17.5%), wheeze (14%) and dyspnea (10.5%). Prevalence of physician diagnosed and self-reported asthma was 5.5% and 9.5% respectively. Frequency of obstructive pattern on spirometry was 28.72% and that of restrictive pattern was 19.68%. After adjustment for age, gender, socioeconomic status, spoken dialect, education, smoking status, height, weight and arsenic in drinking water, FVC was significantly reduced for phlegm (OR 3.01; 95% CI: 1.14 - 7.94), wheeze (OR 7.22; 95% CI: 2.52 - 20.67) and shortness of breath (OR 4.91; 95% CI: 1.57 - 15.36); and FEV1 was significantly reduced for cough (OR 2.69; 95% CI: 1.12 - 6.43), phlegm (OR 3.01; 95% CI: 1.26 - 7.16) and wheeze (OR 10.77; 95% CI: 3.45 - 33.6). Presence of respiratory symptoms was significantly associated with restrictive and/or obstructive patterns after controlling for confounders. Similar findings were observed through linear regression where respiratory symptoms were found to be significantly associated with decrements in lung volumes. Specificity and positive predictive values were found to be higher for all the symptoms compared to sensitivity and negative predictive values. CONCLUSION: Symptoms based respiratory questionnaires are a valuable tool for screening of respiratory symptoms in resource poor, rural community setting.
