Impact of selected clinical pharmacy services on medication safety and prescription cost of patients attending a selected primary healthcare setting: a translational experience from a resource-limited country.

PURPOSE OF THE STUDY: The impact of clinical pharmacy (CP) services on primary healthcare (PH) is less well studied in resource-limited countries. We aimed to evaluate the effect of selected CP services on medication safety and prescription cost at a PH setting in Sri Lanka. STUDY DESIGN: Patients attending a PH medical clinic with medications prescribed at the same visit were selected using systematic random sampling. A medication history was obtained and medications were reconciled and reviewed using four standard references. Drug-related problems (DRPs) were identified and categorised, and severities were assessed using the National Coordinating Council Medication Error Reporting and Prevention Index. Acceptance of DRPs by prescribers was assessed. Prescription cost reduction due to CP interventions was assessed using Wilcoxon signed-rank test at 5% significance. RESULTS: Among 150 patients approached, 51 were recruited. Nearly half (58.8%) reported financial difficulties in purchasing medications. DRPs identified were 86. Of them, 13.9% (12 of 86) DRPs were identified when taking a medication history (administration errors (7 of 12); self-prescribing errors (5 of 12)), 2.3% (2 of 86) during reconciliation, and 83.7% (72 of 86) during medication reviewing (wrong indication (18 of 72), wrong strength (14 of 72), wrong frequency (19 of 72), wrong route of administration (2 of 72), duplication (3 of 72), other (16 of 72)). Most DRPs (55.8%) reached the patient, but did not cause harm. Prescribers accepted 65.8% (56 of 86) DRPs identified by researchers. The individual prescription cost reduced significantly due to CP interventions (p<0.001). CONCLUSIONS: Implementing CP services could potentially improve medication safety at a PH level even in resource-limited settings. Prescription cost could be significantly reduced for patients with financial difficulties in consultation with prescribers.

A Statement of Solidarity on COVID-19 Pandemic 2020 by the South Asian Family Physicians.

The World Organization of Family Doctors (WONCA) is a not-for-profit organization and was founded in 1972 by member organizations in 18 countries. WONCA now has 118 Member Organizations in 131 countries and territories with a membership of about 500,000 family doctors and more than 90 percent of the world's population. WONCA has seven regions, each of which has its own regional Council and run their own regional activities including conferences. WONCA South Asia Region is constituted by the national academies and colleges and academic member organizations of this region namely India, Pakistan, Bangladesh, Nepal, Sri Lanka, Bhutan, and the Maldives. In the background of the ongoing COVID 19 pandemic, the office bearers, academic leaders, practitioners, and researchers of primary care from the South Asia Region have issued a solidarity statement articulating the role of primary care physicians.

Prevalence and alternative explanations influence cancer diagnosis: An experimental study with physicians.

OBJECTIVE: Cancer causes death to millions of people worldwide. Early detection of cancer in primary care may enhance patients' chances of survival. However, physicians often miss early cancers, which tend to present with undifferentiated symptoms. Within a theoretical framework of the hypothesis generation (HyGene) model, together with psychological literature, we studied how 2 factors-cancer prevalence and an alternative explanation for the patient's symptoms-impede early cancer detection, as well as prompt patient management. METHOD: Three hundred family physicians diagnosed and managed 2 patient cases, where cancer was a possible diagnosis (one colorectal cancer, the other lung cancer). We employed a 2 (cancer prevalence: low vs. high) × 2 (alternative explanation: present vs. absent) between-subjects design. Cancer prevalence was manipulated by changing either patient age or sex; the alternative explanation for the symptoms was manipulated by adding or removing a relevant clinical history. Each patient consulted twice. RESULTS: In a series of random-intercept logistic models, both higher prevalence (OR = 1.92, 95% confidence interval [CI 1.27, 2.92]) and absence of an alternative explanation (OR = 1.70, 95% CI [1.11, 2.59]) increased the likelihood of a cancer diagnosis, which, in turn, increased the likelihood of prompt referral (OR = 22.84, 95% CI [16.14, 32.32]). CONCLUSIONS: These findings confirm the probabilistic nature of the diagnosis generation process and validate the application of the HyGene model to early cancer detection. Increasing the salience of cancer-such as listing cancer as a diagnostic possibility-during the initial hypothesis generation phase may improve early cancer detection. (PsycINFO Database Record

Expectations for antibiotics increase their prescribing: Causal evidence about localized impact.

OBJECTIVE: Clinically irrelevant but psychologically important factors such as patients' expectations for antibiotics encourage overprescribing. We aimed to (a) provide missing causal evidence of this effect, (b) identify whether the expectations distort the perceived probability of a bacterial infection either in a pre- or postdecisional distortions pathway, and (c) detect possible moderators of this effect. METHOD: Family physicians expressed their willingness to prescribe antibiotics (Experiment 1, n1 = 305) or their decision to prescribe (Experiment 2, n2 = 131) and assessed the probability of a bacterial infection in hypothetical patients with infections either with low or high expectations for antibiotics. Response order of prescribing/probability was manipulated in Experiment 1. RESULTS: Overall, the expectations for antibiotics increased intention to prescribe (Experiment 1, F(1, 301) = 25.32, p < .001, ηp² = .08, regardless of the response order; Experiment 2, odds ratio [OR] = 2.31, and OR = 0.75, Vignettes 1 and 2, respectively). Expectations for antibiotics did not change the perceived probability of a bacterial infection (Experiment 1, F(1, 301) = 1.86, p = .173, ηp² = .01, regardless of the response order; Experiment 2, d = -0.03, and d = +0.25, Vignettes 1 and 2, respectively). Physicians' experience was positively associated with prescribing, but it did not moderate the expectations effect on prescribing. CONCLUSIONS: Patients' and their parents' expectations increase antibiotics prescribing, but their effect is localized-it does not leak into the perceived probability of a bacterial infection. Interventions reducing the overprescribing of antibiotics should target also psychological factors. (PsycINFO Database Record

The Role of Physicians' First Impressions in the Diagnosis of Possible Cancers without Alarm Symptoms.

BACKGROUND: First impressions are thought to exert a disproportionate influence on subsequent judgments; however, their role in medical diagnosis has not been systematically studied. We aimed to elicit and measure the association between first impressions and subsequent diagnoses in common presentations with subtle indications of cancer. METHODS: Ninety UK family physicians conducted interactive simulated consultations online, while on the phone with a researcher. They saw 6 patient cases, 3 of which could be cancers. Each cancer case included 2 consultations, whereby each patient consulted again with nonimproving and some new symptoms. After reading an introduction (patient description and presenting problem), physicians could request more information, which the researcher displayed online. In 2 of the possible cancers, physicians thought aloud. Two raters coded independently the physicians' first utterances (after reading the introduction but before requesting more information) as either acknowledging the possibility of cancer or not. We measured the association of these first impressions with the final diagnoses and management decisions. RESULTS: The raters coded 297 verbalizations with high interrater agreement (Kappa = 0.89). When the possibility of cancer was initially verbalized, the odds of subsequently diagnosing it were on average 5 times higher (odds ratio 4.90 [95% CI 2.72 to 8.84], P < 0.001), while the odds of appropriate referral doubled (OR 1.98 [1.10 to 3.57], P = 0.002). The number of cancer-related questions physicians asked mediated the relationship between first impressions and subsequent diagnosis, explaining 29% of the total effect. CONCLUSION: We measured a strong association between family physicians' first diagnostic impressions and subsequent diagnoses and decisions. We suggest that interventions to influence and support the diagnostic process should target its early stage of hypothesis generation.

Trends in cardiovascular risk factors among people with diabetes in a population based study, Health Survey for England 1994-2009.

AIMS: We evaluated trends in cardiovascular risk factors in a population-based sample of people with diabetes in England from 1994 to 2009. METHODS: Data were obtained from Health Survey for England for 1994, 1998, 2003, 2006, 2008 and 2009. Participants were aged ≥30 years with self-reported diabetes. RESULTS: The standerdised prevalence of diabetes increased from 2.8% in 1994 to 6.4% in 2009 and the prevalence among males was higher than females throughout. The trend in prevalence was more apparent in manual workers. From 1994 to 2009, mean systolic blood pressure declined from 148 mmHg to 137 mmHg; mean diastolic pressure declined from 80 mmHg to 70 mmHg; mean total cholesterol declined from 6.1 mmol/L to 4.5 mmol/L over the 15 years with linear trends. The proportion prescribed lipid lowering drugs increased from 2.2% to 47.4%. The percentage of current smokers declined from 17.5% to 13.4%. Mean body mass index increased from 27.7 kg/m(2) to 31.6 kg/m(2) with an overall increase of 0.24 kg/m(2) per year. Risk factor trends were generally similar between genders and social classes but the decline in smoking was not significant for men or for manual workers. CONCLUSIONS: People with clinical diabetes have experienced substantial reductions in blood pressure, total cholesterol and smoking over 15 years. Increasing body mass index and persistence of smoking in lower socioeconomic groups, may compromise these improvements.
