13. The impact of government regulation of ambulatory surgical facilities on access to elective surgical procedures

Advances in medical technology have made free-standing ambulatory surgery centres a cost-effective method of delivering health care in the United States. One: Rapid expansion of such centres and duplication of services have raised concerns over rising health care costs, two: leading to government regulation of facilities via a Certificate of Need (CON) law in many states. Three: Such regulation may decrease access to elective procedures. This study investigates access to elective surgical procedures in selected states with and without CON laws. Results of the Health Care Utilization Project were analyzed. Per capita rates of elective carpal tunnel release (CTR) and lumbar discectomy were evaluated in 16 states with CON laws and 5 states without CON laws over the years 2004-2005. Distribution of CTR and lumbar discectomy were analyzed by facility ownership and teaching status, using rates of emergent procedures as a control. Student&#8217;s t-tests compared rates of CTR and discectomy as a function of CON legislation. Two-factor ANOVA extended this analysis to account for teaching environment and facility ownership. Fewer CTR cases were performed in states with CON laws (p=0.014), specifically in government-owned (p=0.012) and non-teaching facilities (p=0.01). No difference was observed in lumbar discectomy rates in states with respect to CON regulation. Distribution of both procedures among teaching and non-teaching centers was independent of CON laws. Facility ownership predicts fraction of these cases performed at an institution,(p < 0.01) and this distribution is influenced by CON regulation, increasing fractions of both types of procedures performed at private, not-for-profit centers (p=0.001, p=0.003 respectively). We conclude that CON laws restrict access to certain procedures, specifically in government-owned and non-teaching facilities. These laws may limit the supply of surgical care, notably by redistributing away from government and for-profit centres. Potential solutions include reinvestigating the need for CON laws, or examining the CON methodology to accurately reflect need. Small NC, Bert JM.

Effect of US State Certificate of Need regulation of operating rooms on surgical resident training

Purpose: Government regulation of health care services helps prevent costs associated with expansion and duplication of services in the United States. Certificate of Need (CON) helps restrict construction of ambulatory surgery facilities and hence controls delivery of surgical intervention, but concern exists about whether this affects resident exposure to an appropriate caseload. This study investigated how CON laws impact on surgical caseload as an index of resident surgical training. Methods: This retrospective study used State Inpatient Data compiled by the Health Care Utilization Project. Mean per capita rates of 26 diverse surgical procedures were evaluated in 21 states with CON laws and 5 states without between 2004 and 2006. The proportion of procedures performed in teaching facilities was also assessed. Student’s t-tests were used to evaluate differences in these parameters between regulated and non-regulated states (a = 0.05). Multivariate analysis of variance permitted evaluation of the types of procedures that underwent shift in location performed. Results: States with CON laws did not differ significantly in procedural rates for any of the investigated surgical procedures; however, such regulation was associated with different trends in teaching center caseload, depending on the type of procedure. Complex procedures, such as Whipple operations (p = 0.14) or resection of acoustic neuroma (p = 0.37), underwent no redistribution. Conversely, common procedures that might have previously been performed in private settings, such as total hip replacement (p = 0.003) or mastectomy (p = 0.01), did occur more commonly in teaching facilities under CON regulation. CON law did not result in relocation of surgical procedures away from teaching institutions. Conclusions: These results suggest that government regulations do not discriminate against teaching facilities. Surgical residents in states with such regulation gain similar or superior exposure to procedures as residents in states without such laws

Impact of US state government regulation on patient access to elective surgical care

Purpose. Rising health care costs in the United States have led to government regulation of services via a Certificate of Need (CON) law in many states. Such regulation may decrease access to elective surgical procedures. This study describes the impact of CON laws on elective surgical care. Methods. This retrospective cohort trial used data from the Health Care Utilization Project, a publicly available, inpatient database. Rates of six elective procedures were compared between 21 CON states and 5 non-CON states (2004-2005). Further, facility type (non-profit versus for-profit), facility teaching status, and median charges were also compared as a function of CON status. Statistical analysis was performed by Student’s t-tests (?=0.05). Results. CON laws did not affect procedure rates (P = 0.11-0.97), but lower charges were found for lumbar discectomy ($16,819 versus$13,493 p=0.04), acoustic neuroma resection ($60,993 versus$46,353, P < 0.001), and microvascular decompression (MVD) for trigeminal neuralgia ($37,741 versus$27,729, P < 0.001) in CON states. Various procedures exhibited a shift from for-profit to non-profit facilities including lumbar disectomy (20% versus 9%, P=0.01), acoustic neuroma resection (5.5% versus 0.2%, P=0.03), MVD (20% versus 3%, P=0.02), and rotator cuff repair (23% versus 10%, P=0.01). CON status had no effect on proportion of cases occurring at teaching facilities. Conclusions. CON laws appear to maintain patient access to elective surgical care while successfully reducing hospital charges. The location of surgery may shift to non-profit centers suggesting preferential certificate distribution, though this only partly explains the decreased charges in states with CON regulation

Cosmetic and Cognitive Outcomes of Positional Plagiocephaly Treatment

Purpose: Positional plagiocephaly is an acquired deformation of an intrinsically normal infant skull by sustained or excessive extrinsic forces. Non-surgical techniques include counter-positioning, supervised prone time and orthotic molding for more refractory cases. Long-term effects of positional plagiocephaly on development remain undefined, and this study evaluated cosmetic and cognitive outcomes of plagiocephaly management. Method: Surveys were administered to parents of patients treated for positional plagiocephaly through the Children’s Hospital of Eastern Ontario. Categorical responses interrogated cosmetic outcome, school performance, language skills, cognitive development and societal function. Pearson coefficient analysis tested outcomes dependency on gender, age, and plagiocephaly side at the 0.05 level of significance. Results: Eighty respondents (51 male, 29 female) were divided as 58 right- and 22 left-sided pathology. Positional therapy was uniformly applied, and a helmet orthosis was utilized in 36% of cases. Median follow-up age was nine years with normal head appearance in 75% of cases. Only 4% of parents and 9% of patients observed significant residual asymmetry. These results did not vary by gender, age or deformity side. Left-sided disease predicted poorer language development and academic performance. Expressive speech abnormality occurred in twice as many patients with left-sided disease (36% versus 16%, p=0.04) along with three-fold greater special education requirements (27% versus 10%, p=0.04). Conclusions: Non-surgical plagiocephaly management achieved good cosmetic outcome among patients in this study. Children with left-sided disease frequently encountered difficulties with cognitive and scholastic endeavors, although the roles of the underlying disease and the treatment measures in this delay cannot be differentiated
