Severity of acute hepatitis and its outcome in patients with dengue fever in a tertiary care hospital Karachi, Pakistan (South Asia).

BACKGROUND: Liver injury due to dengue viral infection is not uncommon. Acute liver injury is a severe complicating factor in dengue, predisposing to life-threatening hemorrhage, Disseminated Intravascular Coagulation (DIC) and encephalopathy. Therefore we sought to determine the frequency of hepatitis in dengue infection and to compare the outcome (length of stay, in hospital mortality, complications) between patients of Dengue who have mild/moderate (ALT 23-300 IU/L) v/s severe acute hepatitis (ALT > 300 IU/L). METHODS: A Cohort study of inpatients with dengue viral infection done at Aga Khan University Hospital Karachi. All patients (> or = 14 yrs age) admitted with diagnosis of Dengue Fever (DF), Dengue Hemorrhagic Fever (DHF) or Dengue Shock Syndrome (DSS) were included. Chi square test was used to compare categorical variables and fischer exact test where applicable. Survival analysis (Cox regression and log rank) for primary outcome was done. Student t test was used to compare continuous variables. A p value of less than or equal to 0.05 was taken as significant. RESULTS: Six hundred and ninety nine patients were enrolled, including 87% (605) patients with DF and 13% (94) patients with DHF or DSS. Liver functions tests showed median ALT of 88.50 IU/L; IQR 43.25-188 IU/L, median AST of 174 IU/L; IQR 87-371.5 IU/L and median T.Bil of 0.8 mg/dl; IQR 0.6-1.3 mg/dl. Seventy one percent (496) had mild to moderate hepatitis and 15% (103) had severe hepatitis. Mean length of stay (LOS) in patients with mild/moderate hepatitis was 3.63 days v.s 4.3 days in those with severe hepatitis (P value 0.002). Overall mortality was 33.3% (n = 6) in mild/moderate hepatitis vs 66.7% (n = 12) in severe hepatitis group (p value < 0.001). Cox regression analysis also showed significantly higher mortality in severe hepatitis group (H.R (4.91; 95% CI 1.74-13.87 and P value 0.003) and in DHF/DSS (5.43; CI 1.86-15.84 and P value 0.002). There was a significant difference for the complications like Bleeding (P value < 0.001), Acute Renal failure (ARF) (P value 0.002), Acalculus cholecystitis (P value 0.04) and encephalopathy (P value 0.02) in mild/moderate and Severe hepatitis groups respectively. CONCLUSION: Severe hepatitis (SGPT>300IU) in Dengue is associated with prolonged LOS, mortality, bleeding and RF.

Culture and quality care perceptions in a Pakistani hospital.

PURPOSE: Organizational culture is a determinant for quality improvement. This paper aims to assess organizational culture in a hospital setting, understand its relationship with perceptions about quality of care and identify areas for improvement. DESIGN/METHODOLOGY/APPROACH: The paper is based on a cross-sectional survey in a large clinical department that used two validated questionnaires. The first contained 20 items addressing perceptions of cultural typology (64 respondents). The second one assessed staff views on quality improvement implementation (48 faculty) in three domains: leadership, information and analysis and human resource utilization (employee satisfaction). FINDINGS: All four cultural types received scoring, from a mean of 17.5 (group), 13.7 (developmental), 31.2 (rational) to 37.2 (hierarchical). The latter was the dominant cultural type. Group (participatory) and developmental (open) culture types had significant positive correlation with optimistic perceptions about leadership (r = 0.48 and 0.55 respectively, p < 0.00). Hierarchical (bureaucratic) culture was significantly negatively correlated with domains; leadership (r = -0.61,p < 0.00), information and analysis (-0.50, p < 0.00) and employee satisfaction (r = -0.55, p < 0.00). Responses reveal a need for leadership to better utilize suggestions for improving quality of care, strengthening the process of information analysis and encouraging reward and recognition for employees. RESEARCH LIMITATIONS/IMPLICATIONS: It is likely that, by adopting a participatory and open culture, staff views about organizational leadership will improve and employee satisfaction will be enhanced. This finding has implications for quality care implementation in other hospital settings. ORIGINALITY/VALUE: The paper bridges an important gap in the literature by addressing the relationship between culture and quality care perceptions in a Pakistani hospital. As such a new and informative perspective is added.

An open study to assess the safety and efficacy of Heprovac-B vaccine 10 mcg-dose for adults.

Heprovac B is a novel recombinant vaccine. There are many vaccines available in Pakistani market but Heprovac B claims to be immunogenic even at 10 meg dose. Aim of the study is to determine whether using 10 meg of Heprovac B vaccine is safe and effective in producing sufficient immunity in Pakistani population. One hundred and twenty five subjects, who fulfilled the Inclusion criteria, were enrolled for the study. Heprovac B was administered in a three-dose regimen given at 0, 1 and 6 months and adverse events were recorded. Immunogenicity was tested by measuring hepatitis B surface antibody one month after each dose received. One month after the 3rd dose 98.7% of the subjects were found to be seroprotected with geometric mean titer of 488.83 mIU/1 after the third dose. Heprovac B, vaccine was well tolerated with minimal reported adverse events. It is safe and 10 mcg is immunogenic in producing antibodies in Pakistani population against Hepatitis B virus.
