Assessing the magnitude and uncertainties of the burden of selected diseases attributable to extreme heat and extreme precipitation under a climate change scenario in Michigan for the period 2041–2070

Table 4 Central estimates of historical (1971–2000) and projected (2040–2070) annual counts and rates (per 100,000 persons) of disease burden and estimated cost attributable to extreme heat (EH) or extreme precipitation (EP) for the State of Michigan

Outcome	Historical Count	Historical Rate	Historical Cost^a	Projected Count	Projected Rate	Projected Cost^a
EH mortality	33	0.46	$42 million	240	2.9	$280 million
EH hospitalizations	28	0.28	$240,000	185	1.6	$1.6 million
EH ED visits	1200	12	$2.2 million	7800	68	$14 million
EP GI illness ED visits	170	1.7	$370,000	220	1.9	$480,000

^aAssuming, per person: $129,000 per life-year [29] and age-specific life expectancies for persons who eventually died of circulatory or respiratory disease [34]; Michigan 2014 renal hospitalization costs of $9000 [21]; Michigan 2014 respiratory hospitalization costs of $8400 [21]; heat-related hospitalization cost of $5400 with additional costs of $1500 among ages 65–77 and $1600 among ages 78 and older {Schmeltz, 2016 #2143;{Kingsley, 2015 #1867}; non-accidental ED visit cost of $1800 and gastrointestinal infection ED visit cost of $2200, based on 2015 median costs [31]
